DIfficillima fuerit parvae hujus Eclipjis obfervatio,
propter obliquam lunte in umbram tzxix Incideu-
tiam, Umbrseque ipfius tenuit&tem, per quam limbam
Luna, media etiam Eclipji, fatis diftinde cernere potui-
mus. Partes ditimetri tunc ab umbra vera deficientes,
propter confufos ejus terminos accurate definire non Ii-
cuit. Diftantiam ergo coepi inter cufpides male definitos,
circa medium defedus, equa di&as partes facile deduci
poffint, & cum erroris minore periculo Coelum habuimus
toto tempore Eclipjis fatis ferenura- Obfervata fxc fe ha-
bent.
